Problems with TeX or Sweave

RStudio cannot find TeX

RStudio uses the existence of pdflatex to verify
that TeX is installed. If you are experiencing problems with
RStudio detecting your installation of TeX, start a new support
discussion and include the output of the following commands from
RStudio console.

> Sys.which('pdflatex')

This may vary depending upon how you installed TeX (MiKTeX, Mac
Ports, etc)

TeX or Sweave file does not compile

Remove spaces from path

TeX does not support paths with spaces. Make sure there are no
spaces in your file name or your username.

Check the log

Check the log file located in the same directory as the .tex or
.Rnw file (the file extension will be .log). This will help you
discover errors in the script.

Test the R code

For Sweave documents, be sure your R code runs without errors
before compiling your pdf. You can test your R code by using the
Source button at the top right of the pane. If you
are having trouble with your R code, the following Knowledge Base
articles may help:
